Lost my genre radio

[the_Demongod]

I recently had a bugged out radio that would say it was playing something different than was actually playing. I deleted the station with the intent of remaking it. But now I can't figure out how I made it. It was a black metal genre radio. But now when I go down to "genre radios" there are only a handfull to choose from, and you can only make artist radios. I can't seem to find anywhere where you can make your own genre radios. How do I get my black metal radio back?

Thanks
